Coffee may make your sweet tooth harder to resist, research says. According to Cleveland Clinic Wellness, participants in a study who drank regular coffee with sugar rated the beverage as less sweet than those who drank decaf with the same amount of sugar. The explanation:

Caffeine “works” by temporarily suppressing the receptors in the brain that promote relaxation and sleepiness. And it so happens that those receptors are also linked to the ability to taste sweetness. It’s not hard to see, then, how regular coffee may encourage you to add extra sugar to your cup or opt for sweet treats on the side.

“Keep that in mind the next time you pour yourself a cup, and pre-plan your accompanying food accordingly,” the clinic advises. Options like eggs or oatmeal are generally better for you than a doughnut anyway.
